Synthesis, Characterization and Catalysis of a Copper(II) MOF Based on 1,3,5-benzenetricarboxylic Acid and Flexible Bis(imidazole) Ligands

A metal-organic framework [Cu(Hbtc)(bmix)(0.5)](n) (1) (H(3)btc=1,3,5-benzenetricarboxylic acid, bmix=1,4-bis (2-methylimidazole-1-ylmethyl)benzene) has been hydrothermally synthesized and characterized. 1 crystallizes in the orthorhombic system, space groups Pbcn, a=1.436 3(1) nm, b=1.477 2(1) nm, c=1.543 5(1) nm, V=3.274 7 (4) nm(3), Z=8, In 1, Hbtc(2-) as a four-connector bridges Cu(II) node, and bmix ligand as a strut modifies its network structure. Eventually, the complex 1 displays a 3D (4,5)-connected net topology with a Schlafli symbol of (4(2).5.6(2).8)(4(2).5(3).6(3).7.8). In addition,the thermal and catalytic degradation of methyl orange in photo Fenton like process associated with complex 1 also were investigated. CCDC: 791521.
